The terminal portions 11 and 12 are inserted until they are formed in the FPC1, The square protrusions 15 and 16 of 2 abut the central protrusion 30. In this way, the terminal portions 11 and 12 of the Fpci 2 are located on the lower arm 5B of the spring-shaped contact 5. That is, the square protrusions 15 and 16 It has the positioning function of the insertion direction. In this embodiment, FPC1 and FPC2 are inserted at the same time, but they can be inserted separately. For example, the terminal parts 11 and 12 of FPC1 and 2 are inserted into the terminal insertion port. In the state of 1A and 1B, when the cover shell 4 is closed, the cover shell 4 will force the terminal parts 11 and 12 'of the FPCI and 2 toward the lower arm 5B of the spring-like contactor 5 to make it contact the spring-like contactor. 5 The lower end of the lower arm 5B is connected. At the same time, the anti-falling protrusion 40 of the cover shell 4 fits into the notch 33 at the same time as the FPC1 The square protrusions 15 and 16 of 2 are engaged. Therefore, when the force to make the FPC1 and 2 fall off from the connector 100 is applied, the respective rear ends of the square protrusions 15 and 16 are in contact with the anti-fall protrusions 40. It is possible to prevent the FPCs 1 and 2 from falling off from the connector 100. The reason for providing the falling-off prevention mechanism will be described here, and the falling-off prevention mechanism is constituted by the falling-off prevention projection 40 and the notch portion 33 as described above. The bullet I-shaped contact 5 holds the terminal portions 1 丨 and 丨 2 with a specific force. The force of the bullet κ-shaped contact 5 holding the terminal portions 11 and 12 is so weak that the terminal portions 11 and 12 are not damaged. The force is sufficient for electrical contact. In this case, when the force that wants to make the FPC1 and 2 fall off the connector 100 has an effect, then the contact between the spring-shaped contact 5 and the terminal U, 12 Friction can prevent FPC1 and 2 from falling off from connector 100. However, if the number of spring-shaped contact 5 (the number of FPC wires) is small,

O: \ 89 \ 89597.DOC -13- ** * '.' _ Country — one or two circle _ _ '' circle '' ....... ... '*. _-' 1233246 due to spring shape The friction between the contactor 5 and the terminal portions 11 and 12 is reduced, so that it may not be able to resist the force that will cause the FPCs 1 and 2 to fall off the connector 100. For this reason, an anti-falling mechanism is provided to prevent The FPCs 1 and 2 fall off from the connector 100. In addition, the number of FPC wires (cores) required by the anti-falling mechanism is 5 or less, and it is more ideal if it is 6 or less.
